同步问题

请问一下如何在mongoDB同步mysql的时候，mysql如何在同步数据的时候添加一个自增主键的列，因为不想使用mongoDB的id做主键，例如mongoDB数据：{
"_id": {
"$oid": "612f17f6dcb465e3ce969545"
},
"name": "aaa"
}
mysql数据：id:1,doc_id:"612f17f6dcb465e3ce969545",name:"aaa"

The issue gives MongoDB and MySQL example records but names no DataX file, test, or entry point. Start by reading the documented MongoDB-to-MySQL synchronization configuration and verify whether generating a MySQL auto-increment column is supported; done would be a confirmed configuration or a clearly scoped implementation request.
